That's exactly what I was trying to install. I just couldn't get it to work. No doubt some simple step I had overlooked, but not being able to install the installer was extremely frustrating.

Download tarball, unpack, run `makepkg`, run `pacman -U <pkg>.tar.gz`. It's all here: https://wiki.archlinux.org/index.php/AUR#Installing_packages

Or the even easier:

#> vim /etc/pacman.conf [archlinuxfr] Server = http://repo.archlinux.fr/$arch #> pacman -Sy yaourt
